The protection of the American flag is indicated in the Flag Code. This is a series of laws specifically made to avoid the desecration of the national flag, and create a basis for national compliance. Not only does this state on how to properly carry and bear a flag of the United States, but also indicates the things NOT to do which may be considered as violations. The US flag is a national treasure and should be rendered the highest form of respect. Anything done that would render the opposite shall be considered a violation of the law and meted with the appropriate sanctions.
Out of the 50 states, there are 48 of which have specific laws that are considered to be under the flag code. Since each state has a certain level of jurisdiction with its internal laws, these vary across the nation. Some are more severe when implementing punishments while some are more extreme in considering some specific stipulations as unlawful. For instance, even a jokingly stated derogatory remark to the American flag is considered a criminal offense.
It is therefore safe to conclude that respect and honor is given to the American flag at all times. Never should there be a public derogatory remark or actual physical defacement. Do not allow it to be dirtied, stepped on, mutilated, or damaged. Keep intentions always in the clear. It is better to play safe and respectful at all times. After all, the American flag is a representation of your own existence anyway.
